“Vincent N Roxxy” is a nasty little piece of B-movie trash that lacks both the verve to grab you as a guilty pleasure and the artistry to be taken seriously as a dramatic thriller. It wastes talented actors who usually have a welcome presence on screen — Emile Hirsch, Zoe Kravitz, Emory Cohen and Zoey Deutch — in barely-there, go-nowhere roles. And it takes place in a thoroughly unpleasant slab of small-town Louisiana populated by idiot lowlifes whose primary characteristics are chain smoking and bad tattoos. My one-star RogerEbert.com review.
